I have a bit of a strange problem, I am trying to determine if a certain MAC address (my xbox 360) is on the network (i.e. on)

The problem is i'm doing it from my Synology Cubestation, which is a powerpc based NAS with an embedded Linux.

I have access to a variety of commands including ping and nslookup, but i do not have things like arp which would be most useful.

I don't mind doing something like pinging everything from 192.168.1.1 to 192.168.1.255, but that doesn't return the mac address. unfortunately my knowledge of the Linuxy network commands are limited so any suggestions welcome.

P.S. if there is another way to determine if my xbox is on the network, those suggestions are welcome too.

what do you mean by "on the network"? If you want to find out if the ethernet interface on your XBOX is working, You can simply looki at the corresponding LED on your switch... Or am I missing something?

You are missing something. I clearly wouldn't be asking if I wanted to tell if my xbox was on. This is all part of a larger scheme.

Hi, this is great thanks, your assumptions were all correct. Your answer is especially great for telling me how to update the local arp cache. A quick ping of every IP on the local subnet works wonderfully.
